. sure of pneumatic tires. f

On the common type of disc wheels the hand holes are made large enoughto reach through with the ordinary type of chuck and inflate the innerdual tire and also the outer dual tire. The disc is somewhat weakenedbecause of the necessity o-f making the hand hole large enough to reachthrough in order to inflate the dual tires. Furthermore, there has beenconsiderable objection to this disc wheel with the necessarily largehand holes, because it does not lend itself to decorative effect andstriping.

The important object of this invention is to provide an inflationchuckassembly attachment with which it is very easy to reach both valves ofthe tires on dualdisc wheels.

With the use of this invention', it is only necessary to put one verysmall hole in `each disc, thereby avoiding any weakening of the disc,and furthermore the disc will lend itself readily to decorative effectand striping;

Other objects and advantages of'this invention will becomeapparentduring the course of the following description, takenpinconnection With the accompanying drawing'wherein is illustrated apractical embodiment of the invention, and in which:

Figure 1 is a transverse section of dual disc wheels having dual tiresmounted thereon, showing a practical embodiment of the invention asoperatively applied to the valve stems of the tires;

Figure 2 is a fragmentary elevation of the device as applied to a valvestem;

Figure 3 is an enlarged longitudinal section through the chuck head asapplied to a valve stem;

Figure 4 is a View taken on the line 4-4 of Figure 1;

Figure 5 is a partial view showing the application of the invention toan air pressure gauge; and

Figure 6 is a partial View in side elevation showing a slightmodification in which the handle is dispensed with.

Referring now to the drawing, and particularly to Figure l, the numeralI designates dual disc wheels having rims 2 mounted thereon and tires 3and 3 mounted on said rims, the valve sleeves 4 and 5 extending throughradial openings in said rims beyond the inner peripheral wall of thelatter and at this point they are bent at right angles, the ends 4' and5 of said valve sleev'es'd andV 5 extending toward each other throughsmall openingsl and 6' in the dual disc wheels I. v

As shown in Figure 1, the pipe or hose 'I which leads from the pump-orsource of `airlsupply'is provided with a chuck or connector 8 which ispreferably the sameas those ordinarilyusedfor making a connection rfromthe hoseto the tire c valve. Y l

In carrying out the invention, We provide a hollow stem 9 having areduced end I0 which is adapted to yremovablyV enter the opening i-n-the chuckv or connector 8 on the free end of air hose l Secured Itotheopposite end of stem 9 is-a -T- i:

withthe hollow stem 9 through channel II `and are controlled by doublecheck valves I5 andv 'I6. These valves are held in the closed positionby the -inside air pressure until suilicient force, for instance a valvestemyis inserted in either one of the openings I3 or I4 to overcome theinside air pressure, thereby opening that particularvalve, Ythe'othervalve remainingY closed during this operation by'reason of the insideair'pressure. It will be understood that any other practical type ofvalve may be used here.

A handle I9 of general L-shape, as seen in Figures l and 5, has aU-shaped cross section, as seen in Figure 4, and leg of this handle issecured near the end I9 of the stem 9 diametrically opposite the chuckhead II. The other leg i 2| of handle I9 acts as a cradle for the hose 1and thereby affords an ideal grip for manipulating as a unit theinflation chuck assembly and the free end of the hose.

A U-shaped clip member I8 is pivoted at its open end to the leg 20 ofthe handle I9 by means of screws or the like 22 and adapted for pivotalmovement whereby the closed end of the clip I8 cooperates with the chuckhead 8 to embrace the same, thus maintaining proper engagement of thestem 9 with the chuck head 8.

Figure 5 shows the chuck valve assembly as used with an air pressuregauge 23 of the standard type for testing the tire pressure. Thispressure gauge 23 has a chuck head 24 in which the end I0 of the stem 9is inserted and held in engagement with said chuck head 24 by thepivotal clip I8. In this instance the leg portion 2I acts as a cradlefor the barrel 25 of the gauge,

thereby affording a handy grip for manipulating as a unit the chuckvalve assembly and air pressure gauge.

In the modication i'n Figure 6 the handle is dispensed with, theengagement of the clip I8 behind the rounded chuck head 8 being reliedon to hold the parts in assembled relation. It will be understood thatthis clip springs over the head 8 drawing it toward the end of the stem9 and snaps behind the head to hold the parts in this region.

The operation of this device is as follows. For inating the tires of adual disc wheel the service attendant grasps the ordinary air hose 'Iwhich has a chuck head 8 on its free end, and inserts the end ID of stem9. The pivotal clip then is rotated until it embraces the chuck head 8,thereby holding the end of the stem in engagement with the chuck head.The device now being properly assembled with the air hose, the attendantgrasps the leg portion 2| of the handle I9 and that portionof the hose'I which rests in the leg portion 2|, orrii the niodcation of Figure 6is used, the hose itself, which serves asa handle. The chuck head II,secured to the opposite end of stem 9, is extended through the smallopening 6 in the disc wheel until the valve sleeve 4 enters the openingI4 of the longitudinal section I2 of the chuck head II thereby openingthe valve I6 and admitting air under pressure to the tire 3. It will benoted that the valve I at the other end of the longitudinal portion I2remains closed during this operation.

Sufficient air having been admitted to the tire 3 the device is thenmoved to the dotted line position shown in Figure 1 until the sleeve 5enters the opening I3, thereby opening the valve I5 and admitting airunder pressure to tire 3. This operation having been completed, thedevice is removed from the air hose 'I by rotating the clip I8 until itreleases the chuck head 8, thereby allowing the end I0 of the stem to beremoved from the chuck head 8.

Totest the air pressure in each tire, the air pressure gauge 23 isassembled With the device in the same manner as that described above.

Thus it will be seen that with this new valve chuck it is very easy toreach both valve sleeves for inating tires on dual disc Wheels and it isonly necessary to put one small hole in each disc to accommodate thisdevice.

While we have shown the preferred embodiment of our invention, it is tobe understood that various changes in the size, shape and arrangement ofparts may be resorted to without departing from the spirit of theinvention and the scope of the appended claims.

What we claim is:

1. An inflation chuck assembly attachment comprising a hollow stem, saidstem constructed at one end thereof to be deta-chably inserted in theusual valve head carried on the free end of an inlating hose or standardtire gauge, means for maintaining proper engagement of the end of saidstem with said valve head, an elongated handle secured to said stem andarranged to receive said inflation hose or tire gauge therealong,whereby the hose or tire gauge and handle together may be convenientlygrasped by the hand `of the operator, a plural outlet chuck head securedto the opposite end of said stem, said chuck head having opposedopenings in its faces to receive the ends of pneumatic tire valvesleeves.

2. An ination chuck assembly attachment comprising a hollow stem, saidstern constructed at one end thereof for insertion in the usual valvehead carried on the free end of an inflating hose or standard tiregauge, an elongated handle secured to said stem and acting as a cradleto embrace, for the greater portion of the length of said handle, saidinating hose or tire gauge, means for maintaining proper engagement ofthe end of said stem with said valve head, said means comprising aU-shaped clip pivotally mounted at its open end near the end of saidstem and having its closed end constructed to embrace said valve head, aT-shaped outlet chuck head secured to the opposite end of said stemdiametrically opposite said handle and extending perpendicular to saidstem, the longitudinal portion of said T-shaped chuck head extending ona line parallel to said hollow stem, said longitudinal portion havingopposed openings in its faces, said openings having check valves thereinand constructed to receive the ends of pneumatic tire valve sleeves.
